Because 135 cannot add hard drives, data cannot be deleted. So the method of mount to the space of another machine is adopted. As follows:

1. Vim / etc/exports on 137

Added: / mnt/data/mongodb 192.168.10.135 (rw,no_root_squash)

Then: exportfs-rv

2. Operate on 135and the space of mount 137is local.

Mount-t nfs-o rw 192.168.10.137:/mnt/data/mongodb / data/mongodb

Add to: / etc/fstab:

192.168.10.137:/mnt/data/mongodb / data/mongodb nodev,rw,rsize=32768,wsize=32768 0 0

[note: I loaded it in the 20.2 server as follows:

192.168.20.21:/home/files / cheyooh/files nfs defaults,rw 0 0

]

3. Stop 135mongodb, kill-2 PID

4. The original startup method: toolbox/services/toolbox-mongodb/bin/mongod-dbpath=/data/toolbox-mongodb/db/-fork-logpath=/data/toolbox-mongodb/mongo27017.log

Change to: toolbox/services/toolbox-mongodb/bin/mongod-- dbpath=/data/mongodb/db/-- fork-- logpath=/data/mongodb/db/mongo27018.log

In this way, the write data space of mongodb has been transferred to 137.
